Abstract:
© 2018 Kvantovaya Elektronika and Turpion Ltd. We consider a protocol of broadband quantum memory on a controlled frequency comb of spectral lines of ring microwave resonators connected to a common strip waveguide. A prototype of this memory is manufactured, on which the room-temperature preservation of microwave pulses with an efficiency of about 3 % is demonstrated. The experimentally obtained efficiency can be enhanced to a level above 90 % using modern microwave technologies and conducting experiments at helium temperatures, which opens a new way for the development of integrated microwave quantum memory.
